Abstract
The utility model relates to a reinforced glass fiber anchor rod, being especially suitable for protecting and supporting the end head of coal face and the tunnel of corrosive territories, composed of a rod body, an anchor head, and an anchor tail. The utility model can be used with the resin anchoring agent cooperatively. The anchor rod end is pointed, pins are arranged in the rod holes equispacedly and obliquitously. The anchor tail has two structure styles, the first one is that a steel jacket is bonded to the anchor tail and nuts are screwed on the steel jacket; the second one is that the anchor tail end is provided with a kerf, a protective cover is arranged on the anchor tail, an external cover is arranged on the protective cover, and a deplanate wedge is driven into the kerf. The utility model has the advantages of light weight, high strength, low cost, powerful anchorage force, easy cutting, and convenient installation and operation; has the functions of anti-corrosion, and can make the resin anchoring agent uniformly mixed.
Description
The utility model belongs to tunnel and coal-face supporting field.
Since developing rapidly of bolt-spary supports, anchor pole consumption cumulative year after year, and with constantly widening of road anchor pole purposes, anchor pole often takes place at fully-mechanized mining working and is involved in the fully-mechanized mining equipment in anchor metal, damages the coal mining cutter coal work can not be carried out smoothly; During temporary lining, there is the shortcoming that is difficult for removing in metallic rod body frangibility not after explosion; When using in the humid area, must do preservative treatment, bad adaptability, because metallic rod body limitation in use, the selection of anchor pole is also to diversified development, existing glass fibre reinforced plastics rockbolts and cement anchoring agent are used, the body of rod adopts and holes at the anchor tail end, structure with the pin stationary steel bushing, reduced the intensity of the body of rod, solidified, and the stability of cement anchoring agent and reliability are relatively poor because the thread-shaped anchor head can not make the anchoring agent evenly mix to reach fully, fallen at the end anchored force of anchor pole, therefore this anchor pole can not satisfy the requirement of mining face under mine supporting.
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of anchored force big, in light weight, intensity height, corrosion-resistant, the novel anchor rod that can cut.
The utility model is made up of the glass fiber reinforced plastic body of rod, anchor head, anchor tail, anchor head is a decussate texture, with the supporting use of resin anchoring agent, the end of anchor pole is a tip, and pin is uniform, crisscross is contained in the body of rod hole, pin quantity is no less than 3~4, and anchor head length is greater than 200mm, and the form of anchor tail has two kinds, a kind of for steel screw bushing is bonded in the anchor pole afterbody, nut is screwed on the steel screw bushing; Another kind of for axially to have joint-cutting at the anchor tail end along the body of rod, nicked sheath is aimed at joint-cutting and is contained in the anchor pole afterbody, and coat suit is on sheath, and flat wedge is squeezed in the joint-cutting.
The utility model has the advantages that:
1, body of rod content of glass fiber is up to 70%, and the tensile strength height can be made into the large-tonnage anchor pole, replaces the support pattern of various shapes, has the intensity height, and the characteristics at the bottom of the cost can be saved steel in a large number, improves the anchor pole performance, and economic benefit is very considerable.
2, anchored force is big; the anchor pole afterbody adopts steel screw bushing and body of rod bonding, does not destroy lever strength, adopts flat wedge urgent; but sheath cover glass steel pole body is not cut off by overcoat; rock bolt head adopts the decussate texture of tip, is convenient to puncture the resin cartridge bag, plays good stirring action; resin anchoring agent is mixed; solidify fully, carrying is fast, has increased the stability and the reliability of bolt support.
3, the glass fiber reinforced plastic material is corrosion-resistant, can cut, and compliance is strong, can be used for the supporting in various tunnels.
4, the fiberglass rod body weight is light, and is easy to install, alleviated labor strength, has good social benefit.
The even anchor structure schematic diagram of Fig. 1, Fig. 2.
Be described in further detail below in conjunction with accompanying drawing: the utility model is made up of the glass fiber reinforced plastic body of rod, anchor head, anchor tail, the body of rod 3 is the glass fiber reinforced plastic pole stocks that adopt formed by extrusion and tension, its content of glass fiber is up to about 70%, and vertical marshalling, the mechanical strength height, anchor head is a decussate texture, with the supporting use of resin anchoring agent, the end of anchor pole is a tip, in the hole that pin is 1 and 2 uniform, crisscross is contained in the body of rod 3 and cement, pin quantity is no less than 3~4, and anchor head length is greater than 200mm; The form of anchor tail has two kinds: a kind of for steel screw bushing 5 sticks with glue agent and is bonded in the anchor pole afterbody, nut 4 is screwed on the steel screw bushing 5, treats can use after bonding adhesive solidifies fully; Another kind of for axially to have joint-cutting along the body of rod 3 at the anchor tail end, treat anchor pole after the down-hole stirring installs, first-class supporting plate is aimed at joint-cuttings with nicked sheath 6 and is contained in the anchor pole afterbody, and overcoat 7 is sleeved on the sheath 6, and flat wedge 8 is squeezed in the joint-cutting and is got final product.
